how to create user profile

Sorry - I didn't have time to come back to this earlier.

With the core user profile module, you can create additional fields (like single- or multi-line text fields, checkboxes, URL, date and some other fields to the user profile. You can make them required (in which case a newly registering user has to fill them out upon registration) and decide if they are publicly visible, or only to the administrators (and the users themselves, of course). You can organize the different fields in categories, which will show up in different tabs of user profiles.

If that is not sufficient for your needs, you can check out the Content Profile module. That provides a new content type named 'profile', which you can extend as needed (via CCK) with additional fields. In the configuration options for that content type (after you've enabled it to be used as content profile for users), you can specify how it's shown on the user pages - only as link, or only teasers, or the full content. Content profile comes with an additional module included (Content Profile User Registration) that allows you to include fields from your newly defined profile content type in the registration process as well.

You can use both (core profile and content profile) modules in parallel (i.e., mix them).

Hope this helps.
